Statistical package for social science version

The Statistical Package for Social Science (version 15.0; SPSS Inc, Chicago IL) was used for all statistical analyses. Significant differences in characteristics and dietary intakes in the categories of total fat intake and SFA using joint categories of higher (≥ median) versus lower (< median) intakes were evaluated using one-way analysis of variance for continuous variables and values were reported as Mean (SD). Chi-square test was used to detect any significant differences in the distribution of participants across quartile categories with regard to qualitative variables.
Odds Ratio (ORs) and their 95 % confidence intervals was estimated for the MetS and its components, according to both unsaturated fatty acids (MUFA and PUFA) and SFA using joint categories of higher median intake versus lower median intakes [22 (link)], by multivariable logistic regression models. In all multivariate models, subjects with lower median intakes of both unsaturated fatty acids (MUFA and PUFA) and SFA were considered as the reference.

Statistical analysis was performed using standardized statistical software (Statistical Package for Social Science; version 19.0; SPSS, Inc., Chicago, IL). Non-normally distributed data were expressed as median (25th, 75th interquartile range). Enumeration data were expressed as frequency, rate, or composition ratio, and tested with the chi-squared test. P values of < 0.05 were considered statistically significant.
